Where do you get these files from? I think it would be best to ask the people who give you these files what the details of the format are. It's very hard to reverse-engineer a file format if you have almost no idea of what the file contains. [ December 01, 2006: Message edited by: Jesper Young ]
The problem is that SPF files are generated from third Party software called Sequencer 4.7 found at http://www.genecodes.com/downloads/PC/Sequencher4.7Demo.zip. They create these files for working out DNA sequences, the problem is that I can see whats in the SPF files by using their software but its far too expensive to buy.

If users wish to see what im on about you can download the Sequencer 4.7 i mentioned above, it has information stored in the SCF format files imported into the projects, plus other information (Some of which we do not need to read).
Also if you send me your e-mail in the private message area I can send you a copy of the all the files used to create the SPF file!
Aha, so you want to reverse engineer a proprietary file format.
First of all, if it's a proprietary format, the company that sells the software might not like it that you're reverse engineering their file format. So what you want to do is maybe not legal.
Second, if you really want to do this you must probably be an expert in the field of genes etc., otherwise you have no idea what you're looking at. Most people on the forum here are not experts in that field.
I don't think you're going to get a solution to your problem here.
ask the people who built the software that generates the files. If they want others to read and write their format they'll have a document for you describing the format in detail. If not you're on your own, and should not expect help as reverse engineering is illegal in many countries and generally frowned upon by honest people even where not as a breach of manners (it's like sneaking into your neighbours' house and reading their mail when they're asleep).
